Zhangzhou Xinkai Welding Equipment is a professional ultrasonic welding equipment company developed by Shanghai Chenfeng Industrial Co., Ltd., which is used in many industries

Common ultrasonic metal welding equipment mainly includes the following:

1.Ultrasonic vibration welding machine: It is a device that uses the heat generated by ultrasonic vibration to weld metals, mainly used for the welding of metal sheets.

2.Ultrasonic friction vibration welding machine: It is a kind of equipment that uses the heat generated by ultrasonic vibration and frictional heat to weld metals, mainly used for the welding of thick metals such as metal pipes and metal bars.

3.Ultrasonic friction stir welding machine: It is a kind of equipment that uses the heat generated by the vibration of ultrasonic reed stool posture and stirring heat to weld metals, mainly used for the welding of aluminum alloys.

4.Ultrasonic coarse key wave orbital welder: It is a kind of equipment that uses the heat generated by ultrasonic vibration and orbital motion to weld metals, mainly used for metal welding of complex shapes.

These devices can realize the welding of metals by controlling the frequency, power and amplitude of ultrasonic waves, which has the advantages of fast welding speed, high weld quality and environmental protection.

New energy vehicle industry. The tabs on the lithium battery pack of electric vehicles that are popular now, as well as the welding of wiring harnesses and wiring harnesses inside the car, and the welding of wiring harnesses and terminals. These welding materials tend to be copper or aluminum with high electrical conductivity, so traditional resistance welding is not possible.

In addition, ultrasonic metal welding has a small heat-affected area, is clean and free of sparks, and is a very safe welding process.

Medical industry. The most typical application is pin soldering on integrated circuits in medical devices. No glue or adhesive is required for the process, but only the bulk material is used for the connection.

Examples include pacemakers for patients and sensors implanted in the body. Ultrasonic welding is also widely used in the manufacture of intravenous catheters, blood gas filters, dialysis machines, valves, and filters.

Electronics and computer industry. Ultrasonic welding is the best connection process for wires and circuits on microelectronic components, which is used in chips, motors, capacitors, flash memory, microprocessors, transformers and other products. The entire welding process welds a thin metal (usually aluminum or copper) with a thick material to seamlessly connect wires and circuits.

It can effortlessly connect circuits on a circuit board, making it ideal for the smartphone and computer industries.

Aerospace industry. In the manufacture of engine parts, non-ferrous metal materials such as aluminum are welded to steel, and the components after welding have high drawing strength, accurate dimensions and beautiful appearance. It also meets the requirements for sealing performance and impact resistance of closed chambers after welding.

Refrigeration industry. Copper pipes have been used as refrigerators and air conditioning cooling systems. Due to the high cost of copper materials, aluminum tubes have also begun to be used. However, regardless of the use of copper and aluminum tubes, ultrasound can be used to weld or seal the thin dust panels.

Advantages: 1) A wide range of weldable materials can be used for the welding of the same kind of metal materials, especially materials with high electrical conductivity and high thermal conductivity (such as gold, silver, copper, aluminum, etc.) and some refractory metals, and can also be used for the welding of dissimilar metal materials with very different properties (such as thermal conductivity, hardness, melting point, etc.), metals and non-metals, plastics and other materials, and can also realize the welding of special structures such as thickness differences and multi-layer foils.

2) The weldment is not energized, no external heating source is required, there are no macroscopic pores and other defects in the joint, brittle intermetallic compounds are not generated, and there are no problems such as molten metal splashing that is easy to occur during resistance welding.

3) The physical and mechanical properties of the weld metal do not change macroscopically, and the static load strength and fatigue strength of the welded joint are higher than the strength of the resistance welding joint, and the stability is good.

4) The oxide film or coating on the surface of the welded metal has little impact on the welding quality, and the preparation of the surface of the weldment before welding is relatively simple.

5) The electrical energy required to form the joint is less, only 5 of resistance welding; The deformation of the weldment is small.

6) There is no need to add any binders, fillers or solvents, and it has the advantages of easy operation, fast welding speed, high joint strength and high production efficiency. The main disadvantage of ultrasonic welding is that it is limited by the power of the existing equipment, so the thickness of the weldment in contact with the upper sound pole can not be too thick, and the joint form can only use lap joints, and butt joints can not be applied.

Disadvantages: One of the main disadvantages of metal ultrasonic welding is that the welding power increases exponentially with the increase of workpiece thickness and hardness, so it is only used for thin parts such as wire, foil, and sheet;

Ultrasonic metal welding is an efficient, high-precision, high-quality metal welding technology, which is widely used in electronic equipment, automobile manufacturing, aerospace and other industries. Here are some of the common products that use the ultrasonic metal welding process:

Electronic devices: Ultrasonic metal welding technology can be used for the connection of cells, such as solar spine grinding or energy panels, as well as the connection of small electronic components, such as the connection of transistor pins.

Automobile manufacturing: Ultrasonic welding in automobile manufacturing is mainly used to connect auto parts, such as car doors, car bodies, roofs, etc. This welding technology can effectively improve the tightness and strength of auto parts, thereby improving the safety and comfort of the car.

Medical devices: Ultrasonic metal welding technology can be used in the production and processing of medical devices, such as the joining of surgical instruments, implants and medical devices.

Aerospace: Ultrasonic metal welding technology is also widely used in the aerospace field. For example, it can be used in the production of components such as aircraft shells, wings, seats, and interiors, as well as in the production and processing of aero engines such as engines, turbines, and missiles.

Pipeline manufacturing: Ultrasonic metal welding technology can be used for the connection of pipelines, such as oil pipelines, natural gas pipelines, etc. This welding technology can greatly improve the tightness and strength of the pipeline, so as to ensure the safe and stable operation of the pipeline.

In a word, ultrasonic metal welding technology is widely used in various fields and has great potential for development. It can not only improve the production efficiency and product quality, but also reduce the production cost, and has broad market prospects.

The ultrasonic welding method uses mechanical high-frequency vibrations to form seams. The pressure of the assembled part is sandwiched between the oscillating sonotrode and the fixed sonotrode and then at right angles to the contact surface, receiving ultrasonic vibration of 20 40kHz. Alternating high-frequency stresses generate heat at the joint interface, resulting in a high-quality weld.

Advantages of ultrasonic metal welding:

1) The welding material is not molten and does not have fragile metal characteristics.

2) Good conductivity after welding, and the resistivity is extremely low or nearly zero.

3) The requirements for the welded metal surface are low, and oxidation or electroplating can be welded.

4) The soldering time is short, and no flux, gas or solder is required.

5) No spark in welding, environmental protection and safety.
